Specification of Letters Patent.

Patented March 16, 1909.

Application filed January 31, 1906. Serial No. 298,840.

To all whom it may concern:

Be it known that I, THOMAS E. URMSTON, a citizen of the United States residing at Cincinnati, in the county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Flask Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. V f

This invention relates to flask heaters and has for its object to provide a device of this character which may be packed in a minimum space and which may be utilized to quickly heat a flask.

A further ob 'ect of the invention is to provide means for securely holding the flask upon the heater and to provide a novel form of draft door for the heater.

In the accompanying drawings: Figure 1 is a vertical sectional view through the invention showing the same in a telescoped position. Fig. 2 is an elevation of the in vention in use, parts being broken away, and, Fig. 3 is a view partly in section, the section being taken on the line 3-3 of Fig. 1.

Referring to the drawings, the numeral 5 denotes a heater preferably formed of sheet metal and of such shape as to telescopically receive a flask 6 which is also formed of sheet metal. Disposed Within the heater 5 is a lamp 7 provided with a burner 8 which is adapted to be closed by means of a screwcap 9 to prevent spilling ofthe liquid fuel, when the device is tilted. The top of the burner 8 lies substantially flush with the top of the reservoir of the lamp in order that the flask 6 may be more completely contained in the heater 5 when the device is not in use. of its walls with an opening through which the lamp 7 may be removed and the said The heater 5 is provided in'one.

opening is adapted to beclosed by means of a door 10 provided with draft openings. The heater 5 has a portion of its side walls cut away as at 18 forthe reception of a dove-tailed block 19 which is swiveled as at 20 to the bottom of the flask 6. 19 is of the same or less width than the flask 6 and is designed to be swung to lie lengthwise of the said flask when the device is a telescoped position. The block 19 is provided with a recess 21 for the reception of one end of a sliding bolt 22, the said bolt 22 being slidably mounted in the turned over upper edge 23 of the heater 5.- This bolt 22 prevents accidental disengagement of the block from the recesses or cut away portions in the heater 5 as will be readily The block understood. The flask 6 is closed by means of a screw cap 24 which is preferably of such size that it may be used as a drinking cup and the said flask is also provided with a handle 25 which is arranged to lie against the said flask when the device is telescoped.

What is claimed is 1. A device of the class described comprising a heater provided with alining openings in its side walls, a flask, and a block swiveled to the flask and arranged for engagement in said openings.

2. A device of the class described comprising a heater provided with alining openings in its side walls, a flask, a block swiveled to the flask and arranged for engagement in said openings, and a bolt carried by the heater and engaged with said block.

In testimony whereof, I aflix my signature, in presence of two witnesses.

THOMAS It. URMSTON.
